Abstract:A contrast material volume of 60 mL (18 g iodine) provides excellent image quality of cerebral multi-detector row computed tomographic angiography comparable to those achievable with 100 and 80 mL.
• Cerebral CT angiography at 70-kVp substantially improved vascular enhancement • Subjective image quality was better at 70-kVp, with lower radiation dose • The volume of contrast media can be substantially reduced at 70-kVp.
• Cerebral CT angiography at 70-kVp substantially improved vascular enhancement • Subjective image quality was better at 70-kVp, with lower radiation dose • The volume of contrast media can be substantially reduced at 70-kVp.
Because of its considerably enhanced potential to depict vessels of the Circle of Willis and its first- and second-order branches, ToF MRA at 7 T may become an important tool in future neuroradiology research and clinical care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
